    <v-container fluid>
      <v-data-table-extended
          :headers="headers"
          :data="data"

          :config="dataTableConfig"

          api
          @update="update"

          @click-delete="deleteUser"
          @click-edit="editUser"
          @click-view="viewUser"
          @click-create="createUser"
      >

      </v-data-table-extended>
    </v-container>
  </v-app>
</template>
<script>
import {VDataTableExtended, Config, VDataTableExtendedCheckbox} from '../../../../../../../../vue/v-data-table-extended/dist/v-data-table-extended.esm';
...
</script>
